INSULATO R.

Applicat on filed April To all whom it may concern Be it known that 1, WILLIAM S. Gone, a citizen of the United States, residing .'at

Visalia; in the county of Tulare and State of California, have invented certain new and useful Improvements in Insulators, of which the following isa specification, reference being had therein toithe accompanying drawing.

To the cable, betwee ,the blocks D, D is secured, in any suitable 'ina'nner, the conductor E to be insulated and supported. As shown, each insulator consists of a short heavy'bar, which may be of porcelain or other simple or oompositeinsulating matewhich are connected at inten .rial, having enlar ed preferably spherical ends I) and rovi edbetween its-ends with a downward y extending {skirting D for keeping a portion of-the block dry. Each end D of the block is held in a divided ring F integral with two plates F, F having, uponthe side opposite the ring, a channel 'to receive the end of one segment of the cable Specification of Letters Patent.

C, clampedin the channel by means of bolts F passing through both plates. The heads D are not clamped fast in the rings but".

form with them freely acting universal joints. The outer segments of the cable may be secured to the cross-arms in any suitable manner. One of the cables C is shown as having two insulating blocks, in series, on

each side of the conductor, and in general the number of blocks may be increased with the voltage where any high tension currents are carried, and thus current of anytension may be safelyicarried with no special appliances whatever.

Fig. 5 showsseveral line wires carried by a preferably insulated framework G supported in a skeleton tower H. The framework may obviously be such as to carry any desired number of wires, and if a well insulated platform be provided for the line-. man, work on these lines may be done without interrupting the current. In any case, lines may be repaired or lines may be-added without disturbing the transmission by other lines. The blocks are here shown with more than one skirting.-

My invention not particular construction, I do not wish to limit my claims to any particular construction.

hat I claim is: 1. As an insulating support for sion conductors, a divided cable having its ends provided with suitable clamps, and a being limited to any high ten bar of rigid insulating material having rounded ends loosely held in said clamps, respectively, substantially as set. forth."

2. The combination with, the rigid block of insulating material having at its ends rounded heads, of the two part clamps each having the ring to engage one of said heads and the recess for clampingtheend o fa cable, and means for detachably binding the two parts of each clamp together, substai'n tially as set forth. I

3. For supporting high tension conductors, a cable having as a segment a bar forming a material part of the cables length and consisting entirely of rigid insulating material, said bar being provided with an inclined skirting adapted to keep a portion of p the bar dry, substantially as set forth.

4. The combination with two widely separated a-rrns suitably supported, of an approximately vertical cable connecting the free'portions 0i. said arms, and a conductor llO seured to the medial poi'fion of said sable, sald cable hzwmg on each side 0:? the cam ductor a segment formmg a matemal portion of thecables length and consisting of a bar of rigid insulating material provided With an inclined skirting to keep a portion Of the bar-dry, substantially as-set forth. H

,5. The combination with a tower provided with Widely separated rigid arms cne above the other, of a cable connecting the free portions of said arms, and a transverse c0nductor secured to the medlal portmn of the MZMM clamps, respectively.
